The SunOS 4.x code, which was almost donated to the

purity since it's not needed to grow and adapt since then. All that
"growth" happened in Solaris. So it's also a bit unfair to compare that
code which was developed over a decade to FreeBSD's.
Yeah, I actually agree with this. The SunOS I love so much didn't
scale at all. Which means it was inherently more simple and easier
to understand.
